PMID:19081070
The Hh reception system consists of a 12-span transmembrane protein, Patched (Ptc), as the Hh receptor and a 7-span transmembrane protein, Smoothened (Smo), as the obligatory signal transducer across the plasma membrane (Ingham and McMahon, 2001). In the absence of Hh, Ptc blocks Smo activity, and full-length Gli proteins are proteolytically processed to generate C-terminally truncated GliR that actively represses a subset of Hh target genes. Hh binding to Ptc unleashes Smo activity, which blocks GliR production and promotes GliA activation.
